I COMBINED DOOR HANGING AND OPERATING MEANS.

Specification of Letters Patent.

Patented July 18, 1916.

To all whom it may concern:

Be it known that we, FREDERIC W. HILD, FRANK P. MAIZE, and WILLIAM L. Coor, citizens of the United States, and residents, respectively, of the city of Portland, county of Multnomah, State of Oregon, have invented a certain new and useful Improvement in Combined Door Hanging and Operating Means, of which the following is a specification.

Our invention relates to doors of street railway cars andof other placesiwhere only a mimmum space is available forthe operation .of the door. Thebrdinary swing door, a, 1s hinged on a vertical axis between the upper andlower horizontal bracket arms ing door requires a considerable, zone of space which cannot always be kept clear;

and sliding doors require pockets in' which to slide the door, for which'space is not always available. The purpose of our invention is, therefore, to provide means for hanging and operating the door in such wise as to reduce the space required for the opening and closing of the door. Since, in street cars, passengers frequently crowd in the vestibule and blockthe space through which the door must pass in being opened and closed, our invention is particularly service able for street cars.

The particular features of our invention will be more readily understood from the detailed description hereinafter given.

In the accompanying drawings: Figure 1 is an elevation of a door supported by our improved hanging and operating means; Fig. 1 is a detail of construction of the door operating part of the device; Fig. 2 is a horizontal section of the door of the pay-asyou-enter street car type, having an exit closed by a single door and an entrance closed by double doors; the broken lines of this figure show all the doors open; Fig. 3 is a perspective sectional view of the upper portion of the door shown in Fig. l, the section being taken approximately on line 33 of that figure; Figs. 4, 5, and 6 are diagrammatic plan views relating to the double ontrance door shown in- Fig. 2, these views being drawn on a larger scale than Fig. 2, so-

as to illustrate more clearly the various phases in the operation of these double doors; Fig. 7 is a detail of the cam groove provided in the top cross member of the door frame, which cam groove serves as a guide element for the vertical pivot at the top'of the door, and in so doing eii'ects the rotation of the doorin its pivots cooperatively w1th the rotation of the shaft on which the door is hung; Figs. 8, 9, and 10 illustrate a simpler type of means for hanging and operating adoor in conformity with the principle of my invention; Figs. 8 and 9 being horizontal sections taken through i the door frame and the wall at one side thereof; Fig. 8 showing the door closed, and, 1

in dotted lines also as fully open; Fig. 9

. showing the door as partly open; and Fig.

10 is a. perspective detail shown .in Figs. 8 and 9. Referring in the first place to Fig. 1, the

of the devices I), c; the axls being located approximately, at the center of the horizontal plane of the door; but in practice the location of the axis will have to be determined by the position desired of the door when open. Both of these bracket arms are allixed on a rotatable door vertical; the bolt andnut I) also serve I to properly aline and suspend the door.

In the door ease, f, is provided a cam groove g, and the roller 1 mounted on a vertical guide pin 9 fastened to the top, of

the door, slides in said cam. groove. Compare Figs. 3 and 7. \Vhen the doOr operating device is operated the shaft (Z will be rotated on its axis, and the upper. and lower bracket arms, 6, 0, will describe parallel arcs of circles in a horizontal plane, thereby moving the vertical axis of the door. The guide pin g, being confined to the course of the cam groove f], will cause the door, a, to rotate on its vertical axis coinrideutly with the rotation of the shaft 1?. The movements of the door will be similar to that of the lefthand door of the double doors illustrated in Figs. 4, 5, and (3. y

In Fig. we have shown the doors commonly used in pay-asvou-cnter street cars, it representing the exit door. and '1 i the two entrance doors. The dotted lines of this fig ure show the doors as open and illustrate the manner in which they move around the controller box 9', which, wherdtlie ordinary types of door-hanging devices are used, would be inthe way. The diagrammatic views Figs. 4, 5, and 6 show the operation of the entrance doors ?1, i. The hanging devices and the operating means for both of the doors, 2', z', are the same and they are similar to the devices supporting and operating-the single door shown in Figs. 1 and 3, and therefore corresponding parts have been given similar letters. p

The utility of our invention and its advantages over the ordinary swinging door are brought out in Fig. 6.-"Tn this view the broken lines A indicate the boundary line of the zone which would be swept by any of the ordinary types of swinging doors, while the dot-and-dash lines B indicate the boundary line of the zone swept by the doors hung and operated by our improved means.

As already mentioned, Figs. 8 to 10 inclusive illustrate a simpler type of the means, embodying the principle of our invention, for hanging-and operating a door. The door j is pivotally supported between an upper arm is and a lower corresponding arm, not shown,'but located similarly to the arm 0 in Fig. 1; and these arms are affixed on the vertical shaft 1, which is rotated by the crank arm m, fixed on the shaft Z and connected by a link m to a hand-lever, not shown. The,

upper arm k is made with a perpendicular projection is, with which is connected one end of a spring at, the otherof which is fastened to the top of the door j by any convenient means. A guide rail 0 is fastened at the top of the door case, and the door is provided with stud rollers 19, p, rotating on vertical pins provided at the opposite ends of the door. When the door operating devices are operated'to open the door the stud roller 39 will bear against the guide rail- 0, due to the action of the spring n. During the opening of the door it will first assume the position in which it is shown in Fig. 9, and then the stud roller 39 will bear against the wall 1] and-cause the door to assume the position in which it is shown in dotted outlines in Fig. 8. Thewall q is provided with a recess '1" for the projecting member 70. It will thus be noted that the movement of the door during its opening and closing is similar to that of the doors shown in the preceding figures, but the devices are somewhat simplified by using a guide rail o,-instead of providing a cam groove 9 in thetop of the door case.

We claim: v 1. in means of the character described, the combination of a vertical rotatable shaft, a pair of horizontal arms rigid on such shaft and alined one above the other, a vertical pivot on the extremity of the lower of said Y arms, a pivot pendent from the'extre'mity of head, said pendent pivot adapted for being relatively shortened and-lengthened, a door provided with a cavity at the top, near the middle, for receiving said headed end of said pendent pivot, a bearing-plate affixed to said portion of the door for the head of said pendent pivot to bear against, a' guide element, means provided on the top of the door for holding the outer end thereof in cooperative relation with said guide element, and means for rotating the shaft.

2. In means of the character described, the combination of a vertical rotatable shaft, a pair of horizontal arms rigid on such shaft and alined one above the other, a vertical pivot on the extremity of the lower of said arms,- a pivot pendent from the extremity of the upper of said arms, thelower end of such pivot provided with a head, said pendent pivot being inserted through the extremity of said upper arm, a door provided with a cavity atthe top, near the middle, for receiving said headed end of said pendent pivot, a bearing-plate affixed to said portion of the door for the head of said pendent pivot to bear against, a guide. element, means provided on the top of the door for holding the outer end thereof in cooperative relation with said guide element, and means for rotating the shaft.

8. In means of the character described,the combination of a vertical rotatable shaft, a pairof horizontal arms rigid on such shaft and alined one above the other, a door pivotally suspended between the extremities of said arms, the suspending means being adapted to hang the door from the upper of said arms and so as not to impose the weight of the door on the lower of said 4. In means of the character described,

the combination of a vertical rotatable shaft,
